FOUNDATION IMPEDANCE FUNCTIONS: THEORY VERSUS EXPERIMENT
A comparative study is reported of the foundation-impedance functions derived from forced-vibration-test data with those predicted from theory for two types of foundations: a rectangular slab and a square slab with piers. The study is part of an investigation of the soil-structure interaction of these foundations during earthquake excitation and the effect of this interaction on accelerograms recorded by strong-motion instruments on them. To quantify this interaction, forced-harmonic-vibration tests were performed on the foundations. Theoretical impedance functions were computed, based on the geometry of the foundations and a layered continuum model of the near-surface soils, which was construted from detailed in-situ velocity data. Data from the forced-harmonic-vibration tests were used to compute experimental foundation-impedance functions. Details of the study and the results are presented.
